If memories are closely related to your experience, the imagination allows complete freedom in the choice of images.
Come up with a short, exciting, action scenario in which you are in the main role. Start to dream, gradually plunging headlong into this scenario. Feel the emotions sharp impressions. Experience the story, and profit in it as in the present.
Come up short, a fantastic scenario in which there are unusual items, paints, and the situation. Give free rein to your imagination. The more unusual places and objects, the better.
These exercises develop and reinforce skills in settings to the images.
